Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a receiving device for red-hot coke in a coke oven, particularly in a coke oven that performs dry extinguishing of coke.

(Prior art) In coke dry extinguishing equipment, the red-hot coke discharged from the coke oven is received by a coke bucket placed on a bucket truck running on rails and transported to a hoisting tower by the bucket truck, and then the coke bucket is hoisted by a crane. The coke is then transferred to the prechamber of the dry extinguishing equipment, the coke discharge gate installed at the bottom of the coke bucket is opened, and the red hot coke is charged into the prechamber.The red hot coke is extinguished by the dry extinguishing equipment, and the sensible heat of the red hot coke is extinguished within the system. For example, it is effectively used to generate steam for power generation in a boiler, but after the red-hot coke has been discharged, the coke bucket is placed on the bucket truck again in preparation for the next kiln discharge from the coke oven.

Thus, the coke bucket is a conveying device that is repeatedly used together with the bucket cart for conveying red hot coke.

The conventional coke bucket cart and bucket cart are the third
As shown in the figure, a rectangular coke bucket 3 with a rectangular coke receiving plate 2 is mounted on a bucket truck 1, which is towed by a train to a coke oven 4, and stopped at a fixed position at the coke oven kiln opening before being discharged from the oven. Furnace 4
It receives the coke 5 pushed out through the coke guide. However, in the existing coke oven, the coke falling point 6 is extremely close to the oven side, and due to the angle of repose of the red-hot coke, the coke after being crushed is biased towards the oven side, and the effective coke volume ratio to the total volume of the coke bucket 3 is It was extremely low.

In addition, the load is unevenly loaded, and it is necessary to install a balance weight on the side of the coke bucket 3 opposite to the coke oven in order to maintain balance when lifting it with a crane in the hoisting tower.In addition, providing a balance weight causes the inconvenience that the coke bucket becomes heavier. It was hot.

To solve this problem, we equipped the coke bucket cart with a rotatable turntable.
A coke bucket trolley on which a coke bucket was placed on this turntable was developed in 1974.
It is disclosed in Publication No. 39483.

According to this technology, a square or circular coke bucket can be placed on the turntable and the turntable can be rotated to receive the cork bucket, making it possible to reduce the capacity of the coke bucket. It is explained that this will eliminate the trouble of falling.

However, since the coke bucket truck disclosed in Japanese Utility Model Publication No. 54-39483 is equipped with a turntable on the truck, debris, floating dust, etc. from the discharge gate gap that occurs when unloading the kiln can be removed from the turntable. The coke lumps or coke powder deposited on the turntable become a hindrance when the coke bucket is placed on the turntable, which hinders the stable placement of the coke bucket and the smooth rotation of the coke bucket. For this reason, it was necessary to remove the accumulated coke by inputting air or using air.

(Purpose of the invention) The present invention improves the disadvantages of the prior art,
The objective is to reduce the weight of the coke bucket and the coke bucket trolley as well as to ensure stable operation.Furthermore, another purpose is to reduce the coke particle size and the coke particle size in the circumferential direction into the chamber when discharging red hot coke from the coke bucket. The aim is to charge coke evenly in terms of quality.

(Structure and operation of the invention) The present invention is an apparatus for receiving red-hot coke discharged from a coke oven. A coke bucket cart provided with a rail is mounted on a bucket cart equipped with three or more rollers arranged in a circular ring and a turning device for rotating the cork bucket cart, and a rail provided on the lower surface of the discharge gate is placed on the roller of the bucket cart. This is a red-hot coke receiving device characterized by being configured such that the coke is placed thereon.

The present invention will be explained in detail below with reference to an embodiment shown in the drawings.

1 and 2 show an embodiment of the present invention.

The coke bucket 3 according to the present invention has a cylindrical or polygonal body and is lined with an inner liner, and has a discharge gate 8 at its bottom, and a discharge gate 8 installed on the steel frame of the trolley at its bottom. It has a circular rail 13 corresponding to the coke bucket tray receiving roller 10, hanging fittings 9 on both sides of the coke bucket, and the discharge gate 8 is a door-shaped discharge gate shown in FIG. It's okay to be.

In the present invention, the circular rail 13 is provided with semicircular rails facing each other in the double-opening discharge gate 8 shown in FIG. Therefore, when the discharge gate 8 is in the closed state, it has a circular ring shape.

On the other hand, the bucket cart 1 is composed of a coke bucket cart receiving roller 10 installed on a steel frame, a turning device 11 for rotating the coke bucket cart, and a hanging metal support stand 12 attached to the steel frame. The turning device 11 rotates the coke bucket via gears, chain wheels, rotating arms, or the like.

The apparatus of the present invention configured as described above receives the red hot coke by rotating the coke bucket, which is placed on the receiving roller with the bucket cart stopped in front of the kiln and is rotated by the rotating device, to receive the coke. As shown in Figures 1 and 2, the red-hot coke deposited in this way has an angle of repose θ ₁ that is smaller than the coke repose angle θ that occurs when the coke is deposited in a conventional rectangular coke bucket. Therefore, no coke loading occurs.

(Effects of the invention) As described above, the red hot coke that has been disposed of by the device of the present invention is almost flat in the coke bucket without being loaded toward the coke oven side. There is no need for a balance weight, and the weight of the coke bucket can be reduced. Furthermore, the non-loaded portion on the side opposite to the coke oven that occurs in a rectangular coke bucket is eliminated, and the effective coke volume ratio is significantly increased, making it possible to downsize the coke bucket.

In addition, three or more bearing rollers are arranged intermittently in a circular ring in the part that supports the coke bucket, eliminating the flat surface on which coke lumps and coke powder accumulate at the bottom of the coke bucket, which stabilizes the coke bucket's placement and rotating operation. You will be able to maintain your sexuality continuously.

Furthermore, in the coke bucket of the present invention, the red hot coke is deposited in the coke bucket while the coke bucket is rotated, so that the coke is not evenly distributed in the coke bucket, and as a result, the coke particle size, coke quality, etc. Evenly accommodated in the circumferential direction. When the red-hot coke encased in the coke bucket is supplied to the dry fire extinguishing equipment in this way, the heat is efficiently recovered when it is exchanged with the inert gas in the chamber, resulting in a great equipment effect. Incidentally, when the discharge gate is formed into a cone shape, segregation of the charged amount and particle size in the circumferential direction within the chamber is less likely to occur, so the effects of the present invention are particularly remarkable.
